Abstract

A head mounted display including two display units is provided. Each display unit includes a display module and an optical assembly disposed in front of the display module. The display module includes a carrier body and a plurality of light-emitting elements. The carrier body includes a plurality of recesses. Each recess has a bottom surface and a reflective side wall connected to the bottom surface. A plurality of the light-emitting elements are located in the plurality of recesses. Each light-emitting element is disposed on the bottom surface of a corresponding recess. The optical assembly is disposed in front of the display module.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A head mounted display comprising:
 two display units, each of the display units comprising:
 a display module comprising:
 a carrier body comprising a plurality of recesses, wherein each of the recesses has a bottom surface and a reflective side wall connected to the bottom surface; and 
 a plurality of light-emitting elements located in the recesses, wherein each of the light-emitting elements is disposed on the bottom surface of one corresponding recess; 
 
 an optical assembly disposed in front of the display module; 
 a plurality of light transparent bodies disposed in the recesses and covering the light-emitting elements; and 
 a plurality of condenser lens elements respectively arranged on the light transparent bodies, 
 wherein each of the light transparent bodies is a cured colloid, and the cured colloid contacts the bottom surface and the reflective side wall. 
 
 
     
     
       2. The head mounted display as claimed in  claim 1 , wherein the light-emitting elements comprise a plurality of micro light-emitting diodes, a plurality of micro organic light-emitting diodes, or a combination thereof. 
     
     
       3. The head mounted display as claimed in  claim 1 , wherein the reflective side wall comprises an inclined surface or a curved surface. 
     
     
       4. The head mounted display as claimed in  claim 1 , wherein each of the light transparent bodies is a light transparent element, and the light transparent element is embedded in one corresponding recess. 
     
     
       5. The head mounted display as claimed in  claim 1 , wherein the condenser lens elements are a plurality of Fresnel lens elements. 
     
     
       6. The head mounted display as claimed in  claim 1 , wherein a thickness of each of the light transparent bodies is smaller than a depth of each of the recesses, and the condenser lens elements disposed on the light transparent bodies are located in the recesses. 
     
     
       7. The head mounted display as claimed in  claim 1 , wherein a thickness of each of the light transparent bodies is equal to a depth of each of the recesses, and the condenser lens elements disposed on the light transparent bodies are located outside the recesses. 
     
     
       8. The head mounted display as claimed in  claim 1 , further comprising:
 a housing comprising two accommodating slots, wherein the two display units are disposed in the two accommodating slots, and a side wall surface of each accommodating slot is a rough surface.
